Gravitational Quantum Bit

Authors: Fran De Aquino
Comments: 3 Pages.

The Quantum Computers use qubits (or qbits), the quanta bits, which can assume values 0 or 1, or a superposition of both. In this work, we propose a new type of quantum bit, the Gravitational Quantum Bit or Gqbit, which can be used as an information unit. The concept of the Gqbit is based on the theory of the Gravitational Electromotive Force (Gemf) [1], which shows that, when an electron absorbs a quantum of energy sufficient strong, the gravitational force acting upon it (its weight) changes of direction. The weight of the electron can assume two fundamental statuses. For up, (gravitational force in opposite direction to the gravity g )and, for down (gravitational force in the same direction of g ). Conventionally, we can then assume that for up, the weight of the electron represents the number 0, and that for down, it represents the number 1, similarly to the spin of the electron, which can be interpreted as if the electron rotates in one direction or the other - in this case, rotation in one direction would represent 0 and, in the other, it would represent 1.

Area Efficient Decoder and Simulation Study Using Quantum Dot Cellular Automata

Authors: Aarthi Nadarajan
Comments: 3 Pages.

The progress and dominance of the microelectronics industry has been based on scaling and maintaining functionality at ever smaller scales. The resulting changes in size and package density have limitations due to the physical laws that govern the transistor paradigm. Quantum dot cellular automata (QCA) offer a solution to accomplish device functionalities at nanometer scales. This paper details QCA implementation with simulation results which intuitively prove they are much smaller than the same circuits in standard CMOS technology. The proposed area efficient decoder in this paper is optimal in terms of usage of number of quantum dot cells with a simpler clocking scheme and good performance. The field of quantum dots is relatively at its infancy with significant opportunities for future growth and real time implementations.

A Machine Prototype to Assist Differently Abled People

Authors: Shiv Kokroo
Comments: 2 Pages. Creative Commons license.

Here, I describe a machine prototype that allows differently-abled people to walk again. The unique feature of this machine is that it can be mass-produced for a very reasonable cost and the hardware/software is mostly open source.
